Rectus Sheath Lesions

Rectus sheath lesions are abnormalities that occur in the rectus sheath, a fibrous compartment that encloses the rectus abdominis muscles of the abdominal wall. These lesions can be caused by various factors, present with diverse symptoms, and require different diagnostic tests and treatments.
